ABSTRACT:
An orthopedic chair particularly adapted for the use of an invalid or patient suffering from disabling diseases such as arthritis, sciatica, or the like. The orthopedic chair includes a movably supported frame assembly that serves to maintain a forwardly and downwardly extending saddle-shaped seat at a desired elevation between a pair of laterally spaced side walls and a back rest. The frame movably supports a pair of laterally spaced channels for longitudinal movement relative to the seat, with the forward extremities of the channels having first and second leg supports pivotally mounted thereon. The frame assembly supports first and second reversible electric motors that drive first and second mechanisms that pivot the first and second leg supports to desired angular positions relative to the first and second channels. First and second electric switch mechanisms are mounted at convenient locations on the first and second side walls to permit the user of the invention to selectively energize either the first and second members jointly or individually to pivot the first and second leg supports to desired angular positions. Due to the configuration of the saddle-shaped seat, the user in the orthopedic chair is at all tims urged into a position where his feet are maintained in contact with foot rests that form a part of the leg supports. The orthopedic chair preferably has a source of electricity, such as a battery, removably mounted thereon in a concealed position.
